Weird problem not convergence

I have this JVC TV and have a problem... for the last couple of months when I switched from any input (i.e. video 1 through digital in) to another input the screen would display either one of three things:
1.A plain grey screen with the bottom of the screen having a bowed black section.
2. A plain green screen with the bottom of the screen having a bowed black section.
3. A really weird vertical scramble sometimes many colors, other times only black blue and green.
4. A screen split vertically in half with one side blank or grey, and the other side scrambled vertically.
5. Plain blue screen.
6. Semi scrambled image in black and white, but looks more like a photo negative.
I have equipment hooked up as follows:
Digital In - DirecTv HD H20 receiver DVI cable
Video 1 - DirecTv HD H20 receiver through component cables.(as a back up)
Video 2 - Playstation 2 with component video
Video 3 - Sony DVD with S-Video
On screen menus work fine
Now, the tv won't even display a picture except for one of the above things. It used to fix itself by cycling the power but now it just doesn't work.
Any help appreciated

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Check for convergence failure. Convergence Gallery Try adjusting convergence in user menu. If convergence display is messed up or adjustments do not work correctly, you have an Intermittent short circuit within an STK IC.

Look at menu screen with an unused input (antenna or video). If menu is stable and clear, TV may be OK and you may have a signal input problem.

If it is not poor quality input signal or convergence problem, someone has to troubleshoot to determine if it is a Video, Processing, Power supply or CRT related problem.

Do you have the remote? You will need to cycle through the inputs to get to video 1 or 3. You might have the buttons on the front of your tv that says tv/video or tv/vcr. If not go down the channels past 1 and it might automatically switch through the video input selections. For any of these solutions have the PS2 plugged into video 1 and turned on. Hope this helps.

I hooked up a Pioneer DVD player to my TV and when I play a DVD the volume cannot be controlled by the TV. It just plays at one level and on the louder side. When I'm watching regular TV and the DVD player is on and playing a disc I start to hear the DVD soundtrack at the same time as the whatever I'm watching on TV. I should not be able to hear anything until I switch over to Video 1. Any suggestions?

The most likely cause is shorted convergence chips and possibly a few pico fuses.
